SAND-TRAP FOR CANALS.

Application led January 25, 1916.l

To all whom t may concern.'

Be it known that I, STEPHEN 7. OnnssY, a citizen of the United States,residing at Rocky Ford, in the county of Otero, State of Colorado, haveinvented a new and useful Sand-Trap for Canals; and l do hereby de clarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to an improved sand trap, designed forconstruction in connection with irrigation ditches or canals and thelike, to carry o sand deposits laterally.

One of the objects of the invention is the provision of a device of thisnature, in which improved, efficient and practical features ofconstruction are involved.

One of the features of the invention is the provision of a concrete orcement ditch or canal provided with transverse V-shaped sand depositpockets, there being only one shown, in the bottoms of which laterallyextending conduits are arranged, to carry off the sand and the like,there being gates in said pockets, through which the water in carryingoff the sand through the conduits may seep or percolate, so that thesand and the like may be carried off without clogging.

In practical fields the details of construction may necessitatealterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth` shown in the drawings and claimed.

In the drawings: Figure 1 is a cross sectional view through anirrigation ditch or canal, illust-rating the improved sand trap orpocket as applied thereto. Fig. 2 is a cross sectional view through thesand trap or pocket on line 2-2 of Fig. 1. Fig. 3 is a plan view of thetrap or pocket, showing the side walls of the irrigation ditch or canal.

Referring more especially to the drawings, 1 designates a canal orchannel having a bottom 2 and the side walls 3 constructed of cement,concrete or the like, all of which canal or channel is sunken in anirrigation ditch or the like 4. The bottom 2 of the canal or channel isdesigned to be provided with a plurality of pockets, depressions ortraps, only one of which is illustrated, and designated by the numeral5. This pocket or trap extends transversely of the bottom of the channelor canal 2, and is V-shaped Specification of Letters Patent.

in cross section', as shown in Fig. 2, and provided with inclined endwalls 6. E1nbedded in the cement or concrete bottom 2 and transverselythereof, but in parallelism with and below the bottom of the pocket ortrap 5 is a conduit or pipe 7, which is closed at 8 at one end, and openat 9 at the opposite end, which open end may terminate at any suitablelocation, so as to carry off the sand and the like. This conduit 7 isprovided with a plurality of upwardly eXtending short branch conduits10, the upper open ends of which are flush with the bottom of the pocketor trap 5, in order to carry off the sand deposits and the like that mayHinged at 11 longitudinally to one of the side walls which are inclinedas shown) of the pocket or trap is a grate 12 having an eye 13, and whenclosed or lowered is designed to engage the opposite inclined side wallof said pocket or trap as at 14:. The water in passing through thechannel or canal carries the sand deposits and the like to the pocketsor traps, where the sand and the like sieve or percolate through theopenings 15 of the grate 12, and are carried off through the eX- tensionpipes 10 and out through the conduit or pipe 7, thereby relieving thewater in the channel or canal of the deposits of sand, sediment, andother foreign material. The member 12 may be in the Yform of theperforated plate or the like, just so long as it is provided withsuitable openings. The eye 13 of the grate is designed to receive animplement whereby the grate may be raised and lowered, or agitated upand down upon its hinged connection, to cause the sand and the like tobe washed off the upper surface of the grate.

The invention having been set forth, what is claimed as new and usefulis:

In combination with a canal or channel constructed of cement or concretecomprising a bottom and side wall and sunken in an irrigation ditch,said canal or channel being provided with a transversely disposed sanddeposit pocket or trap V-shaped in cross section, a conduit extendingtransversely below the channel or canal and in parallelism with andbelow the bottom of the pocket or trap, said conduit having upwardlyextending sand outlet tubes, the upper openl ends of which are flushwith the bottom of the pocket or trap, and a grate having hingeconnections with one of the longitudinal inclinedA side Walls of the Intestimony whereof I have signed my pocket or trap and arranged at ashort inname to this specioation in the presence of 10 terval above thebottom of the pocket or two subscribing Witnesses.
